사랑투잉
Lately, even when I sit still and lean back in my chair, my neck feels stiff and painful. Is it a herniated disc? Is there a self-diagnosis method for a herniated disc? Or simple exercises I can try... My neck hurts so much that it's stressful ㅠㅠ I should go to the hospital, but I always finish late in the evening, so I don't have much time. So, I want to try some stretching during breaks at work, please recommend some!
